Abstract

Eletrochemistry is a broad, useful, and selective technique method in many research fields. Among them, the investigation of performance of electrochemical methods in determination, synthesis and selective reduction/oxidation of different elements and molecules have attracted growing attention due their intrinsic advantages such as selectivity, low cost, and high yield of synthesis. Moreover, electrocatalytic synthesis of organic molecules is known as a green and environmentally benign method. In the present form, electrocatalytic multicomponent transformation of barbituric acid, aromatic aldehydes, and 4-hydroxycumarin was carried out. The electrocatalytic transformation was done in alcohols in the presence of tetrabutylammounium flouride as an electrolyte in an undivided cell containing an iron electrode as the cathode and a Pt electrode as the anode at a constant current leads to substituted chromeno[3’,4’:5,6] pyrano[2,3-d] pyrimidines in good to high yields (54-92%) at room temperature. The yield of reaction was obtained by gravimetric analysis and calculated upon theoretical conversion.

电合成铬[3′,4′:5,6]吡喃[2,3-d]嘧啶的绿色方法
电化学在许多研究领域是一种广泛、有用和选择性的技术方法。其中,电化学方法在不同元素和分子的测定、合成和选择性还原/氧化等方面的性能研究因其具有选择性、低成本、高收率等固有优势而日益受到人们的关注。此外,电催化合成有机分子被认为是一种绿色环保的方法。在这种形式下,电催化巴比妥酸、芳香醛和4-羟基孜然素进行了多组分转化。以四丁基氟化铵为电解液,在含铁电极为阴极、铂电极为阳极的未分裂电池中进行醇类电催化转化,在恒流条件下,可在室温下获得高收率(54-92%)的取代色[3 ',4 ':5,6]吡喃[2,3-d]嘧啶。通过重量分析得到反应产率,并进行理论换算计算。
